title: Persistence of urgency and urge urinary incontinence in women with mixed urinary symptoms after midurethral slings: a multivariate analysis.
abstract: OBJECTIVE
  To determine risk factors for persistence of urgency or urge urinary incontinence following midurethral sling surgery.
  
  
  METHODS
  Prospective cohort study.
  
  
  METHODS
  Tertiary referral Urogynaecology Unit.
  
  
  METHODS
  A total of 754 consecutive women with stress urinary incontinence (SUI) and urgency; and 514 women with SUI and urge urinary incontinence (UUI) who underwent midurethral sling with a mean follow up of 50 months.
  
  
  METHODS
  Women with persistent urgency or UUI at long-term follow up were compared with those whose symptoms had resolved, using multivariate analysis to determine the risk factors for persistent symptoms.
  
  
  METHODS
  Odd ratios (OR) of independent risk factors for persistent urgency or UUI.
  
  
  RESULTS
  Persistent urgency (304/754, 40%) and UUI (166/514, 32%) were common. Coexistent detrusor overactivity (OR 2.04, 95% CI 1.39-3.01), baseline symptom severity (OR 1.41, 95% CI 1.10-1.78) and age (OR 1.03, 95% CI 1.02-1.04) increased the risk of persistent urgency, while transobturator sling surgery (OR 0.61, 95% CI 0.39-094) and concomitant prolapse surgery (OR 0.54, 95% CI 0.38-0.75) decreased the risk. For UUI detrusor overactivity (OR 1.86, 95% CI 1.18-2.93), baseline symptom severity (OR 1.88, 95% CI 1.38-2.56), previous incontinence surgery (OR 2.18, 95% CI 1.28-3.70) increased the risk of persistence, whereas apical prolapse surgery (OR 0.33, 95% CI 0.15-0.70) decreased the risk. Women were more likely not to recommend surgery when they experienced persistent urgency (15.8% versus 2.7%, P < 0.0001) or UUI (24.7% versus 2.9%, P < 0.0001).
  
  
  CONCLUSIONS
  Urodynamic parameters, baseline urgency symptom severity, midurethral sling route and concomitant prolapse operation are important predictors of persistent urgency or UUI following midurethral sling.
